What are structural directives in Angular?

Structual directives are responsible for HTML Layouts, reshaping DOM structure by dynamically adding and removing/manipulating elements.

Structural directives have *(asterisk) preceding the attribute name and no square brackets nor parenthesis. This makes structural directives easy to identify.

Examples for structural directives are as follows.

  • *ngIf,
  • *ngFor,
  • ngSwitch (*ngSwitchCase and *ngSwitchDefault).
